Sahithyan's S1 — Properties of Materials
Ductility
A measure of the degree of plastic deformation at fracture.
Most metals are ductile. Ductile materials have high tensile strength.
Percentage elongation
Percentage reduction in area
Brittle
A material that experiences very little or no plastic deformation.
Brittleness order: Ionic bonds > Covalent bonds > Metallic bonds
Malleability
Ability of a material to undergo plastic deformation under compression.
Ductility & Brittleness
Depends on:
- Composition of the material
- Temperature
